Ah OK....I have just discovered (yesterday evening) this variation of the PSK mode, and I was going to ask the same (sorry for resuming this old topic). I have noticed from pskreporter that there's a certain daily amount of activities using SIM. But it is not possible to log it as SIM in any Logging software.
Do you know if any loggin software is giving this possibility?
To upload in eQSL i did like this: I specified in the QSLMSG the "SIM31" mode together with other QSO details
Just sent an eQSL to CT2KCK hope it's clear what i mean:
QSLMSG <SIM31 - CT2KCK (+05dB) wkg IN3TTL rpt sent +3, 73 fm Italy, GDXs, p.se eQSL>
I gave some explanations here on my blog page:
